Be it known that I, ORSON E. WO0DBUnY,of Madison, in the county of Dane,and State of Wisconsin, have made new and usei'ul Improvements inSash-Fasteniugst and I do hereby declare the following to he afull,-clear, and exact description of the nature, construction, andoperation of the same, sutlicicnt to enable one skilled in the art towhich it appertains to construct and use the saine, reference being hadto the accompanying drawings, which are made part of this specification,and in which-- Figure I is a perspective view .of window and fastener.

Figure 2 is a view of the fastening or cam'. i

Figure 3 is a view of the catch, (perspective.)

The invention consists of a cam, slotted at H D I, forming bearings ateither extremity for the screw or other support, and rendering the camreversible, so as to make it lock either up or down. Fig. 2 willsuiciiently show its shape for anypractical purpose. 4

My' invention further consists in the construction ot' a catch,consisting of a plate or bar of metal, furnished with a bossing orprojection of proper siz'e and shape (as shown in'Y the drawings) uponits face side, and also furnished with spikes on its back or reverseside, at cach end, thus, altogether, forming a peculiar-:shaped staple.-The plate which forms the head of this staple may be made with holes ineach end, and be fastened or attached,`

by means of screws or common nails, to the sash or casing, as the casemay be. It must be fastened at each end in order to prevent the turninground, as it would do if it were fastened only at the middle of theplate. When used upon the casing or stop, which is the best way, thestop may be taken from the window-frame and the catch fitted, and theends of the spikes or nails may be clinched upon the back side of thestop. v

The cam A, figs. 1 and 2, is made of any suitable metal, iig. 2 beingthe proper size for all ordinary windows. The catching orlocking-pointsare at `O for locking the sashl down, and at F for lockingthe sash up. H is the upper end of the slot and cam. '.lh'e catch C,iig. 3, should be made of any strong malleable metal, the plate beingabout double the width of the thickness of the spikes G G, the shoulderbeing all ou one sidc.

They must be put into the stop with the shoulder next the sash. Thisleaves the thickness of the shoulder, from. the edge of 'the stop J J'Jand parting-bead K K to the spikes G G, on the back of catch, andaifordslsuliicient strength for the support of the catch firmly in itsplace while the weight of the sash is upon it. As before said, thespikes are designed to go through' the stop o r parting-bead and clinchon the'backuside ofether, as the case may he. To fix the cam A A uponthe sash, irst press the sash to one sideof the window-frame, then marl:(upon the opposite side oi' the window) upon `the sash justseven-sixtccnths of an inch from the stop, near the middle of said sash,and set the screw for supporting the cam through the slot,and at thismark the point F, fig. 2, being placed next the step J J J, when the comis suspendedA on the screw, as at E, g. 1. One catch must be set ataproper point to lock the sash down, as at L, iig. I; the others atconvenient distances above, for fastening the sash up as desired. p

AThe window may be unlocked by placing the finger at II, fig. l, lowersash, and pressing the cam upward, when it will readily reverse and hangas at E, gfl'. The sash may then be raised to any of the catchesdesired, where it will remain secure. 'lo lower the sash, touch the camatrX, andl swing it outward and upward, when it will reverse and slidedown upon the screw B until stopped at' the point- I. When in thisposition the sash may be lowered to its lowest point, when the point Odrops below the catch C, and the window is locked. This fastening-camwill operate readily upon any ordinary window if the sash will only notfull out of the frame. It inuy also be applied to the stop of the windowinstead of the sash.

.The peculiar shape of the slot at II, and from H to D and I, is shownin gf2, forming o. bea-ring atH and I for the screw B, in opposition tothe catch C, when operating with the points F and O against the catch.

Having described my invention, ,what I cla-im, and desire to secure byLett-ers Patent of the United lStates, is` l 1. I claim the cani,slotted at H D I, forming bearings at either extremity for the screw orother support,-

when the cam is operating against the catchG at the points F or O, allas described and for the purpose specified.

2. I elaixnthe catch C, with theA spikes G G, constructed and used asand forthc purposes hcreinbefore named. I
